To all whom it may concern:

. Be it known that we, ARTHURTREVUR- DAWSON, late lieutenant of Royal Navy, and GEORGE THOMAS BUOKHAM, engineer, residing at 32 Victoria street,.London, England, subjects of the King of Great Britain, have in- Vented certain new and useful Improvements struct acompact carriage which can be easily taken to pieces when desired. I

According to our invention the mounting is in the form of a two-wheeled carriage, of which the trail is composed of twoparallel telescopic tubes suitably braced and strengthened by transverse pieces. The ends of these tubes where they are coupled to the carriageaxle are formed with U-shaped or similar.

brackets adapted to fit uponD-shaped or similar lugs on the axle and to be secured in place by suitable means, such as nuts or screws. The said. trail-brackets are provided with lateral recesses, forming bearings concentric with the axle. The pivot-plate is I formed with a U-shaped' or similar bracket to fit upon the axle between said D-shaped,

lugs. The ends of the said U shaped bracket enter the aforesaid lateral recesses in the trail-brackets and oofiperate therewith in such manner that said top carriage can only be removed from the .wheel-axle, together with the trail-brackets, when the top carriage is in its fully-elevated position. The pivottension or arm, which is connected at its free extremity with the elevating-gear. Said arm has a racer or segment, upon which a clamping-bracket on the gun is capableaof sliding in the training movement of the gun and of being locked in the required position. An

ammunition-tray is suitably connected with the. top carriage and participates in all the -movements of the gun. 5 7

In order that" our said invention may be unite the trail to the axle.

clearly understood and readily carried into inwhich Figure 1 is a side elevationof the mounting with one of the carriage-wheels removed. Fig. 2 isa plan, and Fig. 3 a rear elevation, of

the said mounting. Figs. 4 and 5 are vertical sections, and Fig. 6 is a front elevation, of the carriage-axle, showing more clearly the attachment of the trail'and top carriage to'said axle. Fig. 4 represents the top carriage in its horizontal position, and Fig. 5

said' top carriage in its extreme anglelof ele-- vation. Fig. 7 is a front elevation of the carriage-axle with the-trail and top carriage removed therefrom. Fig.8 is a cross-section on the line 1 1 of Fig. 7. Fig. 9 isa crosssecti'on on the line 2 2 of Fig. 6, and Fig. 10 is a .similar cross-section showing the U- shaped bracket of the top carriage in a dinerout. angular position to that represented in" Fig. 9. v p

A is the-gun. B B'are the parallel tubes composing the trail. 0 is the carriage-axle, and'Dv the pivot-plate of the top carriage. The. said tubes B are'connected together at theirends by across-piece b and are of larger,

diameter than the tubes B, so that the latter are capable of longitudinal adjustment there-' in to enable the trail to be contracted and carried on-a pack-saddle when removed from the axle G. The ends'of the smaller tubes B are united by a cross-pieceor trail-shoe b,

Wh'ich'is provided with a spade] and an eye I) for flimbering up.

b is another cross-piece situated about, half-way of the length of the tubes 13 and serving as a support for the elevating-gear." plate of the top carriage has a rearward exb b are the U shaped trail-brackets, which are socketed into the forward ends of the tubes B and which are adapted to fit over the D-shaped lugs .o of the axle. These trailbrackets areprovided with hinged screw bolts 1)", which can be turned into a position transverse of the axle, in which position theycau be maintained bybutterfiy-nuts b .;o

The said trailbrackets are formed with. the lateraljrecesses b for the reception of the ended of the U ion shaped bracketrl of the pivot-plate D. (See Figs. (3, 9, and 10.) These recesses are concentric with the axle C and are approximately semicircular in shape. The U -shaped bracket of the pivot-plate iits upon the cylindrical portion of the axle between the aforesaid {Ii-shaped lugs c and is capable of angular movement thereon and in the recesses or bearings of the trail-brackets b in order to vary the angle of elevation of the gun.

c c are collars on the axle O, which when the pivot-plate and trail-brackets are in place prevent lateral movement of the parts on the axle.

When the pivot-plate is turned into the position represented by Figs. 5 and 9, the horns or extremities d d of the lei-shaped bracket of the pivot-plate coincide with the horns or extremities 5 b" of the U-shaped trail-brackeis b, Fig. 9, so that when the hinge-bolts are turned. into their open position, Fi t, both the trail-brackets b and the pivot-plate bracket d can be lifted and removed from the axle. When, however, the extremities d of the pi vet-plate bracket occupy any other angular position relatively to the extremities b of the trail-brackets--as, for instance, that represented in Fig. l0--the gap between the extremities d b" is less than the diameter of the cylindrical portion of the axle C, and consequently the said U-shaped brackets cannot be lifted from theaxle. It is only by bringing the pivot-plate into the position of extreme elevation represented by Fig. 5 that the said extremities d b can be caused to coincide with one another, Fig. 9, and therefore it is only in this position of the parts that the trail and top carriagecan be detached from the axle. The gun can therefore be elevated or depressed through all the ordinary angles Without any liability of the parts becoming unintentionally detached. The gun is trunnioned in the cross-head (Z ,'Wl1iQl1 is capable of lateral angular movement about the pivot d of the pivot-plate, Figs. 4 and 5.

d is the rearward extension or arm of the pivot-plate, and (1" is the rod of the elevatinggear, to which it is hinged at its rear end. This elevatingrod extends through a split socket d on the cross-piece Z1 of the trail and can be adjusted longitudinally therein in any desired position and locked by a clamp-haw dle (Z The said split socket is furnished with trunnions d", Fig. 1, about the axis of which the socket and elevating-rod can turn during the elevation or depression of the gun.

d is the racer or segment at the rear end of the arm (Z and d is the clamping-bracket carried by the gun and adapted to slide on said racer when the gun is laterally traversed by the gunner through the intervention of the crutch or shoulder-piece A.

(Z is the handle for locking said clampingroasos bracket in any required position on the said racer.

(1 11 are stops at the extremities of the racer for limiting the extent (if-lateral movement of the gun thereon.

Situated on the right-hand side of the crosshead (1 near the base of the same, is :2. lug e, which supports the ammunition-tray E in a position beneath and in line with the feedblock a of the' gun. The said ammunitiontray E by being mounted on the cross-head participates in all the movements of the gun in. its vertical-and lateral adjustments, and therefore always keeps the feed-belt in proper position relatively to the feed-block.

W'hat We claim, and desire to secure by Letters Patent of the United States, is

1. In a guzrcarriage, the combination with the wheel-axle, the trail and the top carriage, of U-shaped brackets on the trail, Iii-shaped lugs on the axle, means for locking the trailbraekets and lugs together, and a U-shaped bracket on the pivot-plate adapted to rotatably engage with a cylindrical portion 0 2 the axle and with hearings in the trail-brackets, for the purpose specified.

2, In a gun-carriage, the combination with the Wheel-axle, the trail and the top carriage, of til-shaped brackets on the trail, D-shaped lugs on the axle, hinge-bolts'and nuts on the trail-brackets for locking the trail to the axle, anda-U-shaped bracket on the pivot-plate rotatably engaging with a cylindrical portion of the axlebetween the D-shaped lugs there on, and with concentric lateral and gapped recesses in the trail-brackets said recesses being so disposed relatively to the axle that the trail-brackets and pivot-plate bracket cooperate to lock the trail and the pivot-plate to the axle substantially as described.

3. In a gun-carriage, the combination with the Wheel-axle and the top carriage, of a trail composed of two parallel telescopic metal tubes, of cross-pieces connecting together said parallel tub" U-shaped brackets on said tubes to engage with D-shaped lugs on the axle, means for detachably locking said brackets to aid lugs, collars on said axle for preventing lateral movement of the trail on the axle, and a U-shaped bracket on the pivot-plate of the top carriage, engagingwith a cylindrical part of the axle and with semicircular or gappcd lateral recesses in the trailbrackets substantially as and for the purpose specified.

In testimony whereof We have hereunto set our hands, in presence of two subscribing Witnesses, this 30th day of January, 1902.
